A gym in Bank, London, has replaced its dumb-bells with human weights to encourage people to exercise more. Members of Gymbox can choose one of five people ranging from two small folks to a hefty 155kg man. The human weights, who sit on adapted machines, are said to help gym-goers by letting them visualise what they are lifting. They will also shout words of encouragement if requested.
This is ultimate application of visualization theory.
